If you want a simple scanner for starting out and do not need digital (P-25 systems), try the Pro-164 from The Shack. It is a great 1,000 channel scanner and has CTCSS/DCS decode/scan and even when I had programmed a 450-460 MHz LTR trunked system, I got the logic channel order wrong (actually it was put up here on RR by someone that got it wrong and missed a couple freqs), but the scanner actually stopped an gave the logic channel order # on the display. I regret selling it to get my BCD-996XT and BCT-15X. But plan to grad another off ebay or somewhere soon. Even with the BCD-396XT, the PRO-164 is a great second portable and even has 2 battery packs, one for rechargeable and one for alkaline batteries. And you can scan multiple systems, I even had a Moto Type II Hybrid 140 MHz military system in it (they have gone to the P-25 380 MHz South-East DOD system now), but it does Moto I/II/II hybrid as well as EDACS and LTR trunking as well as conventional. Like I said, a perfect starter scanner!
Hope that can help someone, more help than I had, I had to buy crystals when I first started, and at $5 a crystal (frequency), scanning was not cheap back in the day!
